Euharamiyida also known as Eleutherodontida, is clade of early mammals or mammal-like cynodonts from the Middle Jurassic to Early Cretaceous of Eurasia and possibly North America.

[2][3] It is disputed whether or not they are related to the haramiyids from the Late Triassic, such as Haramiyavia.

Some members of the group are known to be arboreal, including gliding forms similar to modern flying squirrels or colugos.

[1][3] The position is often dependent on the relationships of euharamiyids to the Late Triassic haramiyids such as Haramiyavia and Thomasia.
